The calling method is as follows: The DebugStr function is similar to an echo.
DebugStr('$Adv->getContentById($id); $id is advertising number, only one call is made, and the returned content is a string');
echo Adv::getContentById(35);
DebugStr('$Adv->getContentByIdJS($id); $id is the advertisement number, only Call one and the returned content is a JS string');
echo Adv::getContentByIdJS(35);
DebugStr('$Adv->getContentByOrder($id); $id is the advertisement number, only call ID One in reverse order, the returned content is a string');
echo Adv::getContentByOrder(4);
DebugStr('$Adv->getContentByOrderJS($id); $id is the advertisement number, only call ID reverse order One, the returned content is a JS string');
echo Adv::getContentByOrderJS(4);
echo '
'; 🎜>
The code is as follows:

The best ways to send emails using PHP include: 1. Use PHP's mail() function to basic sending; 2. Use PHPMailer library to send more complex HTML mail; 3. Use transactional mail services such as SendGrid to improve reliability and analysis capabilities. With these methods, you can ensure that emails not only reach the inbox, but also attract recipients.

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.

In PHP, the characteristic of a do-while loop is to ensure that the loop body is executed at least once, and then decide whether to continue the loop based on the conditions. 1) It executes the loop body before conditional checking, suitable for scenarios where operations need to be performed at least once, such as user input verification and menu systems. 2) However, the syntax of the do-while loop can cause confusion among newbies and may add unnecessary performance overhead.

Efficient hashing strings in PHP can use the following methods: 1. Use the md5 function for fast hashing, but is not suitable for password storage. 2. Use the sha256 function to improve security. 3. Use the password_hash function to process passwords to provide the highest security and convenience.
